WARNING: IF INSULATION IS USED, THE
FIREPLACE MUST NOT BE PLACED DI-
RECTLY AGAINST IT. INSULATION OR
VAPOR BARRIERS, IF USED, MUST FIRST
BE COVERED WITH GYPSUM BOARD,
PLYWOOD, PARTICLE BOARD OR OTHER
MATERIAL TO ASSURE INSULATION AND
VAPOR BARRIERS REMAIN IN PLACE.
WARNING: DO NOT PACK OR FILL RE-
QUIRED AIR SPACES WITH INSULATION
OR OTHER MATERIAL. NO MATERIAL IS
ALLOWED IN THESE AREAS.
Note: Local codes may not require firestopping
at the ceiling levels for outside chase installa-
tions. However, it is recommended for safety
and the reduction of heat loss.

Note: Do not insulate the chase cavity with
blown or fill type insulation materials.
CHIMNEY HEIGHT
The total height of your completed fireplace sys-
tem from the surface the fireplace rests on to the
chimney top must not exceed 80' (24.4m) and
must also meet minimum height requirements.
Refer to the minimum system height chart.

Chase Enclosure
A chase is a vertical box-like structure con-
structed to surround the fireplace and chimney.

Refer to Figure 2 for a typical chase configura-

Surface
tion. As with all chimney installations, avoid
overhead obstructions such as trees, power
lines, etc. A chase should be constructed and
Outside
insulated just like any outside wall. In a cold
Base
climate, we recommend the base of the chase
should also be insulated between the solid
continuous floor beneath the fireplace and the
chase bottom. Chase insulation in a cold cli-
mate installation is not required for safety.
ASSEMBLY OUTLINE
Before You Start
Check your inventory list to be sure you have all
the necessary parts supplied in good usable
condition. Check also for any concealed damage.
Check the operation of the damper. The damper
is controlled through the use of a control lever
located within the firebox opening at the top
center just behind the firebox lintel ( Figure 3 ).
The control lever snaps into place at the ex-
treme range of motion, up and back in the
closed position. When pulled forward and
down, the damper is open.

LOCATION OF FIREPLACE

Carefully select the proper location for heat

circulation, aesthetics, chimney obstructions
(5.6 m)
and clearance to side wall(s). With proper pre-
planning, a slight adjustment of a few inches

can save considerable time and expense later

during construction and assembly.
Figure 4
Carefully consider the position of the fireplace
opening with respect to the location of adja-
cent or nearby stairwells, bath or kitchen ex-
haust fans and/or return air registers for forced
air furnaces/air conditioners that could cause
a smoking fireplace condition if the house is
tightly insulated.
When locating the fireplace, consideration must
be given to combustibles and final finishing.
See Figure 5 and confine the final location of
combustible finish materials to the "Safe Zone".
